Supermarkets are packed full of family dynamics, cranky teens, demanding children, debate and rows over price and wafer thin vs regular ham. Now, the nation’s obsessions and habits are revealed in Lidl’s new ad campaign by Chemistry, which follows Irish couples, siblings and families around as they carefully – and not so carefully – negotiate their way through the weekly shop.

Chemistry’s latest ad campaign ’TrolleyCam’ allows viewers to have a nose into people’s shopping habits, choices, and of course, the rows that ensue when opinions differ over what to buy, how much to spend, and if, indeed, newborn babies really go through 70 nappies a week.

The innovative new ad campaign follows six real families around Lidl as they do their weekly shop – from a young couple expecting their first child to a mother with her two adult sons.

The filming took place in four stores across Ireland, where the campaign is running across TV, online, print, radio, digital, and Out of Home platforms, planned by Mediaworks and Source out of home.
